Young Idealism

The Teacher Who Believed A Fired-Up Educator Tatsuji Chibiki teaches social studies and leads Class 3 with faith in collective ideals. He believes students and teachers can shape their school community through loyalty. The Fatal Blindness His ideals help sustain the denial of Misaki Yomiyama’s death. Chibiki later regards this faith as the trigger that opened the Death Gates.

Witness to Recurrence

The Pattern Emerges From Rumor to Record Chibiki watches the disasters continue in years when he is not directly responsible. He begins making notes because memory itself proves unreliable. Personal Accountability When he becomes head teacher again in 1976, the deaths strike his class directly. His professional identity becomes inseparable from the phenomenon’s victims.

Retreat to the Library

The Librarian’s Exile Leaving Teaching Fear of becoming the next victim and guilt over failing students lead Tatsuji Chibiki to abandon classroom teaching. The Secondary Library He remains at the school as librarian, choosing observation over direct participation. The library becomes both refuge and archive, a controlled space beside the uncontrollable phenomenon.

The Emergency Protector

Returning to the Lodge A Practical Rescue Tatsuji Chibiki drives Ikuo Takabayashi’s relative to the hospital during an asthma attack. When he returns, the lodge is already burning and students are being murdered. Physical Courage He subdues Mieko Numata and orders Koichi Sakakibara to flee. The former teacher becomes an active protector rather than a distant observer.

The Final Witness

Memory’s Last Guardian Reconstructing the Truth Tatsuji Chibiki helps confirm that Reiko Mikami had been absent from the restored records and that the disasters have ended. An Impossible Responsibility He remains one of the few people capable of understanding what happened, though even his knowledge is threatened by the Memory-Erasure Rule.
